Joy Villa -- a Trump supporter who wore a "Make America Great Again" dress to this year's Grammys -- said in an interview Friday that Corey Lewandowski "smacked" her bottom after posing for a photo with her at the party to celebrate Trump's first year in office.

She also alleged that when she told Lewandowski -- who was fired by the Trump campaign in June 2016 -- that she could report him for sexual harassment, he responded: "Go ahead, I work in the private sector," before slapping her again.
